Improvement in ice-cutting machines

operation, by the sub-lever Bzand link Di, the combinationlcontrolled by the lever-A, having its fulcrum sustained bythe stand O2, which is `bolted to frame.

l -flftuhen bolt the uprights I1 In `to the frame at foot and fconnect the tops together with a cross-tie. In `these nprights the bearings arel formed for the main shaft d. Ou" this shaft are keyed the balancefwheels f f and toothed wheels g g.

ties running from the rear uprights.` In these up'- rights the guides for the cross-head n are formed;

also, the bearings'for the crank-shaft e. Y

The toothed pinions h h and cams i i are keyed in` proper positions to receive and transmit the power.

The cross-headn2 is nicely fitted to the guides' i'n,

uprigh'ts, and is -also provided with a. ivrist for the connecting-rod al, constructed in the usual manner,`

by whichv thecross-head n is united to the Crank-shaft effrom which it receives itsmotion. Onjth-is crosshead the jaws or saW-'holdersare cast, inwhich the end of saw S is'bolted.

f io give greater security to the working of the. saw

the guide Ris bolted underneath the frame, andso arranged that a flange or 4guide sits each side of the f l saw that keeps its actionvertical, while the guide also shears against` the back of saw and keeps it yto its-Work.-

` To feed the saw` up to the icethe shoe m isvattached to thelever k by a hinge-joint. In this shoe av steel toe is set at a desired angle. To in surc its working thespringdv/,is addedl l ,The lever fh receives its motion' from the adj usting- `cam 13 on crank-shaft e, aud is heldv against the cam 'lhecam"i` is slotted to change the throiv of cani e tosuit circumstances.

y u To giye uniform width tothe cut the vgauggge D is l set to follow in finished out made by the sawthrough m gaugecan be adjusted'to give any width l of ice desired.

Man-ner of Operation. Firsitthere is a "suitable'openingr cut through the `iceand the saw set down through and bolted in jaws of cross-head. The power vis applied to the wheels f by the handles x x, thence to the saw S'byfthe wheels \g, pinious h, or shaft e, giving'a `reciprbcating motion to tliesaw 1S. The cams 'i t', operating the levers k f connected with feed-shoe m, forcethe toe into the ice `and carry the machine foifward. The direction of the `machine ischange'd" bythe level-LA'. By setting the gauge P the machine willvcut an even width of ice."

The advantages of my inventionare:

First, it cuts completely through the ice at one operation. f

Second, it is self-feeding, and can be easily adjusted to .give a large or short cut, according to the thickness of the ice.

Third, the facility with which it can be turned to saw back and forth on the ice.

Fouith, I can apply either animal, manual, or steampower to operate my machine.

What I claim as my invention, and desire to secure by Letters Patent, is-
